Radiator relief valve



Dec. 31, 1929. A. Buss RADIATOR RELIEF VALVE Filed Aug. 11, 1927 T m mm w m w A TTORNE Patented Dec. 31, 1929 UNITED STATES AUGUST BUSS, OF DETROIT, MICHIGAN RADIATOR RELIEF VALVE Application filed August 11, 1927. Serial No. 212,159.

My invention relates to a new and useful improvement in a radiator relief valve, and has for its object the provision of a valve of this class which will be simple in structure,

economic of manufacture and highly eflicient in use.

Another object of the invention is the provision of an automatically operated relief valve in which the air may be permitted oscape from the radiator so as to increase the heating efficiency of the radiator.

Another object of the invention is the pro-' vision of a relief valve consisting of a minimum number of parts which may be mounted in the radiator, or a projection formed on the radiator so as to be normally concealed from view.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawings form a part of this specification and in which,

Fig. 1 is a side elevational view of a radiator embodying the invention.

Fig 2 is a sectional View taken on line 22 of 1.

Fig. 8 is a sectional view taken on line 3-3 of Fig. 2.

Fig. 1 is a side elevational view of a radiator showing the invention mounted in aboss formed thereon.

Fig. 5 is a fragmentary sectional view of Fig. 4.

AS shown in the drawings, I have illustrated a radiator comprising a plurality of intermediate sections 9 and leg hearing or end sections 10. A return pipe 11 is illustrated for delivering steam to the radiator sections and a vent or relief pipe 11 is shown communicating with the end section 10, this being the usual structure of a radiator.

In the form shown in Fig. 1, in the end section 10 I have provided an inwardly projecting boss 12 which is formed cup shaped and provided in its base with an opening 13 communicating with the interior of the section. A plug 14 is threaded into this cup shaped member and provided with a central opening 15 formed therein. It will be noted that the plug does not extend fully to the base of the cup shaped member but has its inward end spaced therefrom. Positioned on the base of the cup shaped member so as to cover the opening 13 is a disc 16. In use when steam is being delivered to the radiator and it is desired that the air in the radiator sections be permitted escape, the disc 16 will lift from its seat so as to permit escape of the air through the opening 13, around the disc 16 and through the opening 15. When the pressure becomes great in the radiator, the disc 16 will engage the lower surface of the plug 14 so as to close the opening 15. While this disc 16 serves to automatically permit vent to the radiator it will at the same time, because of its closing the opening 13, prevent entry of air into the radiator through these openings, thus adapting itself peculiarly well to a vacuum system.

In this form it will be noted that the air relief is contained wholly within the radiator body so that the appearance of the radiator is altered but a very little degree and ara- 7 diator is provided with an automatic relief vent in which the valve or vent is practically concealed.

In the form shown in Fig. 4 and Fig. 5, I have illustrated the end section 10 of the radiator provided with a boss 17 in which is formed the socket 18 threaded on its inner surface for reception of the plug 1 1', this plug having the opening 15' formed therein. Communicating the interior of the end section 10 with the socket 18 is the passage 19 which is normally closed by the disc 16 operating in the manner mentioned. The advantages of this vent are those which are present in the form shown in Fig. 1 excepting that the boss 17 is formed on the end section 10.

While I have illustrated and described the preferred form of my invention I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In combination with a radiator, a cupshaped portion of said radiator projected inwardly of said radiator and having an opening formed in its base communicating with the interior of said radiator; a plug mounted in said cup-shaped portion having a passage formed therein; and a disc mounted in said container for closing communication between said passage and the interior of said radiator and between said passage and cup-shaped portion, said disc being mo'v able within certain limits in said container.

2. In combination with a radiator, a container formed on and extending downwardly from the upper side of said radiator and having an opening formed in its base in communication with said radiator; a plug mounted in said container having a central opening formed therein; and a disc movably positioned in said container adapted for opening and. closing communication between said passage in said plug and the interior of said radiator.

3. In combination with a radiator, a cup shaped member formed on and projecting inwardly of said radiator and having an opening formed in its base communicating with said radiator; a member threaded into said cupshaped member and having an opening formed therein; and a disc mounted between the upper surface of said base and the inner end of said member, said disc being movable in said cup shaped member and adapted for opening and closing communication between. the opening in said base and the opening in said member.

In testimony whereof I have signed the foregoing specification.

AUGUST BUSS.
